To investigate the effects of stellar feedback on the gravitational state of giant molecular clouds (GMCs), we study CO and CO ALMA maps of nine GMCs distributed thro…
Emission lines due to ionizing radiation from a compact object in the remnant of Supernova 1987A
C. Fransson, M. J. Barlow, P. J. Kavanagh +31
The nearby Supernova 1987A was accompanied by a burst of neutrino emission, which indicates that a compact object (a neutron star or black hole) was formed in the explosion. There…
